Knowledge on the validity of the Strengths and Difficulties Questionnaire (SDQ) among adolescents is limited but essential for the interpretation of SDQ scores preceding the diagnostic process. This study assessed the predictive and discriminative value of adolescent- and parent-rated SDQ scores for psychiatric disorders, diagnosed by professionals in outpatient community clinics, in a sample of 2753 Dutch adolescents aged 12-17. Per disorder, the predictive accuracy of the SDQ scale that is contentwise related to that particular disorder and the SDQ impact scale was assessed. That is, 24 logistic regression analyses were performed, for each combination of DSM-IV diagnosis [4: Attention-Deficit/Hyperactivity Disorder (ADHD), Conduct/Oppositional Defiant Disorder (CD/ODD), Anxiety/Mood disorder, Autism Spectrum Disorder (ASD)], informant (3: adolescent, parent, both), and SDQ scale(s) (2; related scale only, related scale and impact scale). Additional logistic regression analyses were performed to assess the discriminative strength of the SDQ scales. The results show both fair predictive strength and fair discriminative strength for the adolescent- and parent-reported hyperactivity scales, the parent-reported conduct scale, and the parent-reported social and prosocial scales, indicating that these scales provide useful information about the presence of ADHD, CD/ODD, and ASD, respectively. The SDQ emotional scale showed to be insufficiently predictive. The findings suggest that parent-rated SDQ scores can be used to provide clinicians with a preliminary impression of the type of problems for ADHD, CD/ODD, and ASD, and adolescent for ADHD.
关于青少年 Strengths and Difficulties Questionnaire（SDQ）的有效性的知识是有限的，但对于在诊断过程之前解释 SDQ 分数至关重要。本研究评估了青少年和家长评定的 SDQ 分数在预测和区分 2753 名年龄在 12-17 岁的荷兰青少年的精神疾病方面的价值，这些精神疾病由社区门诊的专业人员诊断。对于每种 DSM-IV 诊断[4：注意力缺陷/多动障碍（ADHD）、品行/对立障碍（CD/ODD）、焦虑/情绪障碍、自闭症谱系障碍（ASD）]，评估了与特定障碍内容相关的 SDQ 量表和 SDQ 影响量表的预测准确性。也就是说，针对每个 DSM-IV 诊断[4：注意力缺陷/多动障碍（ADHD）、品行/对立障碍（CD/ODD）、焦虑/情绪障碍、自闭症谱系障碍（ASD）]，进行了 24 项逻辑回归分析，信息提供者（3：青少年、家长、两者）和 SDQ 量表（2；仅相关量表、相关量表和影响量表）。还进行了额外的逻辑回归分析，以评估 SDQ 量表的区分强度。结果表明，青少年和家长报告的多动量表、家长报告的行为量表以及家长报告的社交和亲社会量表具有较好的预测强度和区分强度，这表明这些量表分别提供了有关 ADHD、CD/ODD 和 ASD 存在的有用信息。SDQ 情绪量表的预测能力不足。研究结果表明，家长评定的 SDQ 分数可用于为临床医生提供 ADHD、CD/ODD 和 ASD 的问题类型的初步印象，青少年则用于 ADHD。
